DESCRIPTION    [Toc]    [Back]

     The puc driver provides support for PCI communications cards
containing
     simple  communications  ports,  such as NS16550-family (com)
serial ports
     and standard PC-like (lpt) parallel ports.   The  driver  is
called
     ``universal'' because the interfaces to these devices aren't
nearly as
     well defined and standard as they should be.

     The driver currently supports the following cards:

           Dolphin Peripherals 4014 (dual parallel)
           Dolphin Peripherals 4035 (dual serial)
           SIIG Cyber 2P1S PCI (dual parallel and single serial)
           SIIG Cyber 2S1P PCI (dual serial and single parallel)
           SIIG Cyber 4S PCI (quad serial)
           SIIG Cyber I/O PCI (single serial and single parallel)
           SIIG Cyber Parallel Dual PCI (dual parallel)
           SIIG Cyber Parallel PCI (single parallel)
           SIIG Cyber Serial Dual PCI (dual serial)
           SIIG Cyber Serial PCI (single serial)
           SIIG Cyber 8S PCI 16C850

           VScom PCI 400H (4 port serial)
           VScom PCI 410H (4 port serial and 1 port parallel)
           VScom PCI 800H (8 port serial)

           VScom PCI 400S (4 port serial)
           VScom PCI 800L (8 port serial)
           Exsys EX-41098 (4 port serial)

Actiontec 56K,
                   and others)
           US Robotics 3CP5609 PCI (modem)

           Syba Tech Ltd. PCI-4S2P-550-ECP (4 port serial  and  2
port parallel)

           Boca Research Turbo Serial 658 (8 port serial)
           SUNIX 400x (1 port parallel)
           SUNIX 401x (2 port parallel)
           SUNIX 402x (1 port serial)
           SUNIX 403x (2 port serial)
           SUNIX 405x (4 port serial)
           SUNIX 406x (8 port serial)
           SUNIX 407x (2 port serial and 1 port parallel)
           SUNIX 408x (2 port serial and 2 port parallel)
           SUNIX 409x (4 port serial and 2 port parallel)

     The driver does not support these cards:

           Dolphin Peripherals 4006 (single parallel)
           Dolphin Peripherals 4025 (single serial)
           Dolphin Peripherals 4078 (dual serial and single  parallel)

     but support for them (and for similar cards) should be trivial to add.

     The port locator is used to identify the port (starting from
0) on the
     communications  card  that a subdevice is supposed to attach
to.  Typically,
 the numbering of ports is explained in a card's hardware
documentation,
  and  the port numbers used by the driver are the same
as (or one off
     from, e.g., the manual uses ports numbered starting from  1)
those described
 in the documentation.

HISTORY    [Toc]    [Back]

     The  puc  driver first appeared in NetBSD 1.4.  OpenBSD support was added
     in OpenBSD 2.7.

AUTHORS    [Toc]    [Back]

     The puc driver was written by Chris Demetriou.

BUGS    [Toc]    [Back]

     The current design of this driver keeps  any  com  ports  on
these cards from
     easily  being  used  as  console.  Of course, because boards
with those are
     PCI boards, they also suffer from  dynamic  address  assignment, which also
     means that they can't easily be used as console.

     Some  of  the cards supported by this driver have jumper-selectable com
     port clock multipliers, which are unsupported by this  driver.  Those can
     be  easily  accommodated  with  driver  flags, or by using a
properly scaled
     baud rate when talking to the card.

     Some of the cards supported by this driver, e.g., the  VScom
PCI-800, have
     software-selectable  com  port  clock multipliers, which are
unsupported by
     this driver.  Those can be accommodated using internal driver flags, or
     by  using  a  properly  scaled baud rate when talking to the
card.

     Some ports use an lpt driver other than the machine-independent driver.
     Those  ports  will  not be able to use lpt ports attached to
puc devices.
